Hi,
I'm in a building (after the service) and have a feeder to a 45kVA step down transformer to go from 600-480V for some equipment. The transformer was already bought as delta-wye. The transformer will connect to a fused disconnect on the secondary side, then out to equipment. None of the loads require the neutral, so I would like to bond the neutral per 250 in the transformer, then take the three phases and a ground out to the disconnect and equipment. Any reason we are required to also bring the neutral? I can't see a safety reason or anything in the Code. Any faults would be cleared by the grounded conductor and overcurrent protection. Thanks for any input!
